Art Deco Set of "Swallows" Ashtrays

A Fabulous pair of matching SWALLOWS with an Art Deco feel to them. These are in brass with silver or nickel plating. The ashtray pans have lost most of their plating but otherwise the condition is excellent. I would say this pair is from around the 1930’s but could be earlier . Measurements are 4½ x 4 inches at the base and about 5 inches in height.
